Harvest ready or not by trichomes

Whats the best tool to view trichomes? What should they look like when ready to harvest? Here is one sample. Outdoors in OH


Trichomes should be cloudy and some amber on the buds not sugar leaves. When they become cloudy your in the harvest window. Some do 10-15% amber, some 50/50 depends on if you want a more energy feeling or couch lock which comes with more amber. This is what I use, they cost around $25 and work very well.
